I took my dd 2.10 to a new play group today. She was building a tower which consisted of numbered blocks 1-10. Dd picked up the 6 and was turning it upside down and said "mummy is this a 6 or a 9?". Just I was about to answer, another mum muttered "god can't she tell the difference yet". She was clearly trying to be discreet but I heard, scooped up dd and left. Am I just weak or would that upset anyone else?
